Penned in by the districts of Mokotów, Ochota and Śródmieście this park represents prime real estate, and right now much of the land is subject to sky-high bods from nasty real estate developers. Hands off we say, and not just because drinking in Pole Mokotowskie’s countless bars is one of the highlights of summer, it's also a great place to ride a bike, skate, jog or just relax. Prior to WWII it was used as a military parade ground, and then from 1910 as one of Europe’s first airports. It was here that the Polish aviators Żwirko and Wigura began many of their aerial adventures, and by 1921 passenger flights linking Warsaw with Paris (via Prague and Strasbourg) were commonplace. The opening of Okęcie Airport in 1933 sounded the death knell for the airport, and today the Mokotów Fields serve as a popular summer spot for suburbanites, as well the venue for public events such as the annual Earth Festival. The area has been embraced by the city as a natural area and a lot of effort has recently gone into making it more resemble a modern park, including outdoor fitness equipment, playgrounds, public toilets, creating a large pond and other landscaping works.
